Application tiled December 4, 1900. yeral No. 38,688. (No model.)

To all whom it may concern: A

Be it known that I, ALBERT ENNIs HENDER- SON, clergyman, of the village of Woodbridge, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Roller-Bearings, of which the following is a specification.

My invention relates to improvements in roller-bearings; and the objectof the inven-` tion is toproduce a roller-bearing in which the friction will be reduced to a minimum and which is capable of a ready and accurate adjustment; and vit consists, essentially, of an outer sleeve and an inner sleeve secured on the axle-arm or rotating part by internal nuts, the inner sleeve fitting such axle or rotating part and having situated peripherally outside of same an annular recess, and, further, of rollers provided with conical reduced ends, which have their bearings in a corresponding form of recess in rings situated at each end of the rollers and located in the annular recess, the parts being arranged and constructed in detail as hereinafter more particularly explained.

VFigure l is a sectional perspective View of my preferred form of roller-bearing, showingv the outer sleeve as the rotary part. Fig. 2 is a cross-section on the line a b through Fig. l'. Fig. 3 is an alternative form. Fig. 4 isa crosssection on the line a b of Fig. 3. Fig. 5 is an alternative form. Fig. 6 is a cross-section on the line a2 h2, Fig. 5. Fig. 7 is a detail of the ring-cage shown in Fig. l.

In the drawings like letters of reference in-v dicate corresponding parts in each figure.

A is the arm of an ordinary axle, which in this instance is supposed to be stationary, and B is a tapered sleeve which fits said tapered arm, being held against the shoulder C by means of the end nut D fitting on the reduced end a ot the arm A.

E is the inner dust-cap, which is internally threaded at e, as shown.

F and F are external collars or nuts, which are iitted over the threaded ends h and b of the tapered sleeve B, respectively.

vG is the external sleeve or rotating part in this instance, which is screwed at one end on the ends of such rollers.

into the internal thread e in t-he dust-cap E and at the opposite end into the internal thread e' of the end dust-cap E'.

. H and H' are internal nuts or collars, Which are externally threaded and fit into the internal threads g and g, respectively, located at the ends of the sleeve G.

It will be noticed that the nuts F and F and H and H are provided with the interior flanges f f and h h', respectively, which form shoulders whereby the minorannular end recesses h2 are provided, as indicated. Within these recesses are located the end rings I,

which are connected together by the cross-f rods z', so as to form acage. On the interior faces of the rings I I, I provide the conical recesses t" i.

J indicates rollers, which are provided with th econical reduced ends j, which extend into the broader conical recesses i', so that the apex of the conical reduced ends j iits into the broader apex of the recesses t', thus keeping the rollers J from contact With each other and at the same time minimizing the friction A The outer ends of the rollers J lare located in close proximity to the ends of the fianges ffand h 71/,respectively.

The sleeve or rotating part G may form or be fittedinto the hub of the Wheel of a vehicle,and therefore rotate upon the roller-bearings constructed and arranged in the annular recess G', peripherally outside the sleeve B, or as an alternative the rotating part may be the axle A and its sleeve B, and the stationary part or boxing may be the sleeve G. It is of course not essential as to which part rotates; but in either case it will be seen that from the construction that I have described the rollers are kept separated fro rn each other in a simple manner, and the grinding action on the end of the rollers is practically eliminated on account of the peculiar construction of the reduced tapered ends fitted into the broader tapered recesses, which I have described.

In Figs. 3 and 4 Ishow an alternative form, in which I provide the end rings I I Without any connecting cross-rods I. I provide instead, however, separate minor rollers t2,

which have reduced conical ends 3, which fit l of the nuts and circumferentially between into broader conical recesses l in the rings I. The rollers J' in this case I preferably provide with end pintlesj, which are located outside the flange of the rings I, and thereby the rollers are held in place as well as separated. In this case also the rings I' are stationary in relation to the sleeve G and are provided with diametrical projections 6, which fit in to the corresponding longitudinal grooves g2 in the sleeve G', so as to hold such ring rigid with the sleeve G. The bearing of the rollers J' in this case is removed from the internal periphery of the sleeve G onto the rollers 2.

In Fig. 5 I show another alternative forni, in which I provide end rings l2, which are held in place by the internal nuts h3 and h, which abut the outer faces of the rings I2, as shown. The bearing-rollers J2 in this case have conical reduced ends j, which fit into broader conical recesses 7, as indicated, the conical recesses 7 being situated concentrically closer to the center in the rings I2 as compared with the recesses in the rings I in Fig. 3, thereby throwing the rollers at the outside away from the interior of the sleeve G, but radially upon the sleeve B, upon which the bearing in this case is made.

In the three forms described it will be noticed that the same essential characteristicsp are maintained, and it may be possible also to still further vary the forms without departing from the spirit of my invention.

Vhat I claim as my invention is- 1. The combination with the arm or axle and the sleeve fitting thereon and provided with threaded ends and means for holding the sleeve in position, and the external sleeve or rotating part provided with the endinternal threads, the end collars or nuts tted onto each threaded end of the internal sleeve and provided with inwardly-extending flanges, the end collars or nuts fitting within each end of the external sleeve and provided with inwardly-extending flanges, and forming with the fianges on the collars of the nuts fitting on the internal sleeve end annular recesses, ofthe rollers fitting between the inner fianges the sleeves and provided with conical reduced ends and the end rings fitting within the end annular recesses and provided with broad conical recesses to receive the points of the conical reduced ends of the rollers and means for holding the end rings from spreading from each other as and for the purpose specified.

2. The combination with the arm or axle and the sleeve fitting thereon and provided with threaded ends and means for holding the sleeve in position, and the external sleeve or rotating part provided with the end internal threads, the end collars or nuts tted onto each threaded end of the internal sleeve and provided with inwardly extending iianges, the end collars or nuts fitting within each end of the external sleeve and provided with inwardly-extending fianges, and forming with the fianges on the collars of the nuts fitting on the internal sleeve end annular recesses, of the rollers fitting between the inner ianges of the nuts and circumferentially between the sleeves and provided with c0nical reduced ends, and the end rings fitting within the end annular recesses and provided with broad conical recesses to receive the points of the conical reduced ends of the rollers, means for holding the end rings from spreading from each other and the dust-caps internally threaded and fitted onto the externally-threaded ends of the outer sleeve as and for the purpose specified.

3. The combination with the arm or axle and the sleeve fitting thereon and the external sleeve and rotating part, of the external nuts or collars secured on the ends of the internal sleeve and the opposing internal nuts or collars secured in the ends of the external sleeve and the friction-rollers occupying the annular space between the end nuts or collars and abut-ting the same whereby the sleeves are kept in proper relative position longitudinally as specified.
